Health insurance is more than a safety net – it’s a shield that keeps you from sinking when life throws a medical curveball. But many get stuck wondering: Why is one person’s premium so low while another’s is sky‑high? In India, the formula behind that number is influenced by many moving parts. In this blog, I’ll break it all down—step by step—with real talk, examples, and actionable tips so you don’t overpay or get blindsided later.
1. What Is a Health Insurance Premium?
Think of the premium as your membership fee for access to medical coverage. It’s the amount you pay—yearly, half‑yearly, quarterly, or monthly—to keep your policy active. In return, the insurer guarantees to cover (within policy limits) healthcare costs when you need them.
It’s the backbone of the insurance model: risk pooling. Many people pay premiums, a few make claims, and the insurer balances it out.
2. Why the Premium Matters
Your premium isn’t just a cost—it’s a reflection of the level of protection you get. A paltry premium often means restrictive coverage, loops you through fine print, or leaves you paying huge co‑charges. On the flip side, an overly expensive premium may give features you never use.
Understanding how the premium is calculated helps you:
-
Pick plans that fit your risk profile
-
Spot where you’re overpaying
-
Understand trade‑offs (coverage vs cost)
-
Negotiate or shop better
3. Key Factors That Influence Premiums in India
Here’s the meat of it: what goes into that number? Each insurer may weigh these a little differently, but in India, these are universally important. (Adapted from the factors listed in the ComparePolicy article) ComparePolicy
Age
One of the most significant levers. Younger people are healthier on average, so their premium is lower. As you age, the risk of illnesses, hospitalizations, and chronic conditions increases, so insurers charge more.
Medical / Health History
If you have past illnesses, surgeries, chronic conditions, or repeated medical claims, the insurer views you as higher risk. That increases your premium. Conversely, clean health records work in your favor.
Lifestyle Habits
Smoking, excessive alcohol, risky sports or occupations—these raise your premium. Insurers often treat smokers as a higher class of risk and add loadings.
Sum Insured & Coverage Scope
A “sum insured” is the maximum the insurer will pay. The higher that number, the more your premium. Also, including extra benefits (day‑care surgeries, OPD, maternity, mental health, alternative treatments etc.) increases cost.
Family Size & Plan Type
-
Individual Plan – covers only you.
-
Family Floater – one policy that covers multiple family members. The premium is generally higher than a solo policy, but more efficient than multiple individual ones.
Adding more members or dependents raises the premium. For children, often lower, but adult dependents cost more.
Location / Geographical Risk
Healthcare costs vary regionally. In metro cities or high cost areas, hospitals charge more. Insurers factor that in. Also, areas with more disease prevalence or environmental risks may attract higher premiums.
Network Hospitals & Tie-ins
A plan with a wider network hospital base gives you better access but may cost more. Insurers may charge more for covering remote or premium hospital tie-ups.
Add-ons, Riders & Extra Benefits
Extra features like maternity cover, OPD benefits, wellness programmes, international coverage etc. add to the premium. You pay extra for extra flexibility.
4. Premium Rating Models: How Insurers Price You
Insurers generally use one of these “pricing models” or blends of them:
Community-Rated Premiums
Here, everyone in a certain community or risk class pays the same (or similar) premium. This is simpler and promotes fairness—lower risk and higher risk are averaged out.
Experience / Risk-Rated Premiums
Premiums are personalized based on your medical history, claim history, age, etc. If you’ve had frequent claims, your premium may go up more than someone else of the same age.
No Claim Bonus (NCB)
To encourage claim-free years, insurers often reduce your premium (or increase your sum insured) for each year you don’t claim. It’s an incentive and helps moderate pricing over time. ComparePolicy
5. How Waiting Periods & Exclusions Affect Premiums
Many policies impose waiting periods before certain benefits kick in (for pre‑existing conditions, maternity, specific surgeries etc.). If your policy has long waiting periods or strict exclusions, insurers might reduce your premium because they limit their risk.
If you demand zero waiting period (or minimal ones), expect to pay more.
6. How Insurers Handle Pre‑Existing Conditions
Pre‑existing conditions (PECs) are health issues you already have before buying insurance (diabetes, hypertension, past surgeries). Insurers often:
-
Exclude them entirely
-
Impose waiting periods (1, 2, sometimes more years)
-
Charge “loading” (extra percentage) on premium
-
Offer them only as special benefit after certain years
If you disclose PECs, the insurer will price you accordingly rather than reject you later.
7. Tips to Keep Your Premium in Check
You can’t control everything, but you can influence a lot. Here are practical strategies:
Start Early
Buy health insurance when you’re younger and healthier. The premium is lower, and you lock in coverage before age or health issues jump.
Opt for Family Floater Wisely
If you have dependents, a well‑structured floater might cost less than multiple individual policies. But don’t overdo it—cover only necessary people.
Choose a Reasonable Sum Insured
Don’t over‑insure just for show. Instead, match coverage to realistic, worst‑case medical expenses in your region. Add top-ups if needed.
Keep Healthy Habits
Non‑smoking, lighter alcohol use, regular checkups—these may reduce costly surcharges over time or qualify you for lower claims history.
Shop & Compare
Use aggregator sites or go direct to insurers. Compare not just premium but the benefits, exclusions, network hospitals, renewability etc.
Use Riders Judiciously
Only choose add-ons you are likely to use (maternity, OPD). Unnecessary ones inflate the premium for minimal use.
Look for Loyalty / No-claim Discounts
Stay with an insurer that offers discounts or better benefits for renewals and building trust over years.
8. When It Makes Sense to Opt for a Higher Premium
Sometimes paying more upfront is smart:
-
If you want more extensive coverage (maternity, OPD, foreign hospitalization)
-
If your medical history calls for extra protection
-
If you want less co-pay and more comfort (private rooms, higher room rent)
-
If the policy gives you mobility across cities
In those cases, that higher premium is an investment in peace of mind.
9. Pitfalls & Red Flags to Watch Out For
-
Too low premium? It might mean weak coverage or many exclusions.
-
Fine print overload: Exclusions for “investigative treatments,” “experimental therapies,” etc.
-
Hospital network: If your nearby hospital isn’t in it, coverage is limited in utility.
-
Renewability issues: Some policies may not allow lifelong renewals.
-
Hidden co-pay, sub-limits, and room rent capping: You might pay extra for ICU, specialized surgeries.
-
Short waiting periods or low benefits in 1st year: Beware policies that start strong but weaken later.
10. Real‑Life Illustrations
-
Example 1: Rahul, age 28, buys a ₹5 lakh policy. His premium is low because he’s young, healthy, no claims. As he enters his 40s, the same coverage would cost significantly more due to age and possible health changes.
-
Example 2: Sita and her husband opt for a family floater instead of two individual policies. The floater cost is somewhat higher than one individual policy, but far cheaper than two separate ones. The trick is managing how many dependents you include.
-
Example 3: Arjun has mild hypertension (a PEC). His insurer charges a premium with a loading percentage and enforces a 2-year waiting period before hypertension‑related claims are accepted. This balances risk for insurer and coverage for Arjun.
11. Final Thoughts
Health insurance is a long game, not a one-time purchase. The premium you pay reflects the balance insurers strike between risk and reward, between you and the pool of policyholders. Understanding what drives that premium helps you be a smarter buyer—not just the cheapest, but the best value.
Start early, shop smart, read the fine print, and tailor your coverage to your real needs. Over time, the difference in premiums can translate into thousands saved—or thousands gained in benefits when you need them.
FAQs
Q1: Why do premiums rise drastically after a certain age?
Because medical risk increases. Older age correlates with more chronic disease, weaker immunity, and higher hospital usage. Insurers price in that risk aggressively.
Q2: Can quitting smoking lower my premium?
Often yes. Many policies classify smokers at a higher risk and add surcharges. If you quit and maintain non‑smoker status for a defined period, insurers may reclassify your risk. But you’ll need documentation or proof.
Q3: Is a higher sum insured always better?
Not always. High sum insured is useful in truly serious cases. But if your medical environment rarely demands it, you might pay for coverage you don’t use. It’s better to align sum insured with realistic worst-case expenses for your city/region, and top-up later if needed.
Q4: What is “co-payment” and how does it impact premium?
A co-payment is when you bear a portion of the cost in each claim (e.g. 10% of the bill). Choosing a higher co-payment reduces your premium, because you share risk. But it increases your out-of-pocket burden when you claim.
Q5: Should I always go with the insurer offering the lowest premium?
No. The cheapest policy may hide weak network, exclusions, bad claim settlement in the fine print. Always check network, exclusions, renewability, claim settlement ratio, and the insurer’s reputation—not just premium.
